2016 was an incredible year for the band with another massive No.1 single 'Shout Out To My Ex', and their album 'Glory Days', shooting straight to No.1 on the Official Albums Chart. The record has spent a total of four weeks in the peak position and is the quickest selling album in the UK charts by a girl group since Destiny’s Child’s Survivor in 2001. It is also the longest-reigning girl group No.1 album of the millennium.
